The console object has <^>time()<^> and <^>timeEnd()<^> methods that help with analyzing performance of pieces of your code. You first call <^>console.time()<^> by providing a string argument, then the code that you want to test, then call <^>console.timeEnd()<^> with the same string argument. You'll then see the time it took to run the code in your browser console. Here's an example:
console.time("Time this");
for (var i = 0; i < 10000; i++) {
// Your stuff here
}
console.timeEnd("Time this");
Most of the time code will execute too fast to be able to draw conclusions, so you'd most likely want to run your code in a for loop that goes through thousands of iterations.
Use this only in development mode and remove these calls in code that's going into production.
